AUTOMOBILE CULTIVATOR WITH ROTATIVELY-DBIVEN CULTIVATING-DISKS.

Specification of Letters Patent.

Application filed November 11, 1911'.

Patented Mar. 11, 1913.

Serial No. 659,692.

To all whom at may concern Be it known that I, ,MARCEL LANDRIN, 'L citizen of the Republic of France, and a resident of Place Mantoue, at Soissons, Department of Aisne, France, have invented certain new and useful Improvements in Automobile Cultivators with Rotatively- Driven Cultivating-Disks, of which the following is a specification.

This invention relates to improvements in automobile cultivators in which the cultivating disks, rotatively-driven by the engine of the tractor, are mounted upon a frame pivoted to the tractor-frame. These improvements comprise the following features:,(1) The cultivator-frame is connected to the tractor-frame by a universal pivot device, in order to allow the tractor to oscillate in accordance with the irregularities of the ground without affecting the working position of the cultivator-frame. (2) The shaft carrying the cultivating disks is adjustable in direction in relation to the line of travel. These improvements are represented upon the annexed drawing, in

Figure 1 is an elevation of the rear portion of the cultivator. Fig; 2 is a corresponding plan. Fig. 3 is an end view in section upon line 3-3 of Fig. 2. Figs. 4

and 5 are details in longitudinal and trans verse section, showing the device connecting the cultivator-frame to the tractor-frame.

The mold-disks a are mounted upon a spindle a at the rear of a triangular frame formed by tubes 6 b fixed to a shell or casing b and braced by a tube 6 forming a bridge above the mold-disks. The connection of this cultivator-frame to the frame 0 of the tractor is effected by the said shell I) which can oscillate upon the pivots d d of a crown (1 (Figs. 4: and 5). This crown d can oscillate upon the pivots e e of a ,second crown or ring eitself adapted to turn freely around ashell or hollow piece 1 fixed to the tractor-frame 0 (Figs. 4 and 5).

The driving" shaft 9 operates the molddisks a by means ofa pinion g pinions g 9 upon a perpendicular shaft 9 and a pimon g' keyed upon the shaft of the mold disks; this shaft 9 is divided, the two parts being connectedby a Garden joint g, the perpendicular and horizontal axes of which lie in the respective planes of the corresponding pivots d d and e e.

The angle made'by the shaft 1; of the mold-disks with the 17m, oftravel can be altered by means ofa rod h universally pivoted to an arm integral with the bridge and to a bar 0' fixed to the tractor-frame c,- this rod consists of two portions with right and left hand screw threads connected by a correspondingly screwed sleeve which allows of varying the length of the rod and therefore the inclination of the of the mold-disks in relation to the direction travel. This manner of connection (by versal joint g and a pivoted rod h) allows the tractor to oscillate in accordance with the inequalities-of the ground without affecting the position of the mold-disks. A suitably inclined wheel j runs at the bottom of the furrow and prevents side movement. The position of the shaft 7" carrying this .wheel can be adjusted according to the position of the disk-supporting shaft by means of sockets fixed upon the tubes b b by screws. Rollers '5 adjustable in height limit the depth of cultivation.

' A winch k operated by the engine allows of raising the cultivator frame for the maneuvering and transport of the cult-ivator. The cultivator-frame can easily be separated from'the frame of the machine by dismounting the axes of the Cardan joints, so as'to provide a simple tractor.

What I claim and desire to secure by Letters Patent is: Y

1. An automobile cultivator comprising a tractor frame, a cultivating frame, a shaft rotating in the cultivating frame, cultivating members mounted on said shaft, a shell fixed to the cultivating frame, a shell fixed to the tractor frame, a Cardan joint connecting the two shells, one element of the said Cardan joint being connected with one of the shells, and the other element bein able to turn relatively to the other shell, and means for actuating the cultivating'members.

2. An automobile cultivator comprising a tractor frame, a cultivating frame, a shaft rotating on the cultivating frame, cultivatin' members mounted on said shaft,- a shell fixed to the cultivatin frame, a shell fixed to the tractor frame, a ardan joint connecting the two shells, a driving shaft rotating in the shell fixed to the tractor frame, an actuated shaft rotating in theshell fixed to the cultivating fra me,-a Cardan joint connecting the saidtshafts, and means for transmitting the motion of the actuated'shaft to the cultivating members.

3. An automobile cultivator, comprising a tractor frame, a cultivating frame, a rotating shaft. in the Cultivating frame, cultivating members mounted on said shaft, a shell fixed to the cultivating frame, a shell fixed to the tractor frame, a Cardan joint connecting the two shells, a driving shaft rotating in the shell fixed to the tractor frame, an actuated shaft rotating in the shell fixed to the cultivating frame, a Cardan joint connecting the said shafts, means for transmitting the motion of the actuated shaft to the cultivating members, a rod articulated with the cultivating frame and with the tractor frame, and means for regulating the length of the eaidu'od. v

4. A cultivator, comprising a tractor provided with a frame having an engine thereon, a cultivating frame, a shaftmounted to rotate on the cultivating frame, cultivating 7 said frame, a shell carried at the front of the cultivator frame, a second shell carried by the tractor frame and extending within the first shell, a universal joint connection between the said shells, and means for actuating the cultivating members from the engine of the tractor and including a divided shaft, and a universal joint connecting the members of said shaft 6. In a cultivator, a tractor provided with a frame having an engine thereon, a triangular cultivator frame, a shell or casing carried at thefront of the cultivator frame, a

shell carried by the tractor frame at one side thereof, a universal joint connection between the said shells, a shaft at the rear of the cultivator frame, cultivating members carried by said shaft, means for adjusting said shaft to va the inclination thereof relative to the direction of travel, and means for actuating the shaft carrying the cultivating members from the engine of'the tractor.

'7. An automobile cultivator, comprising a tractor provided, with a frame having an engine thereon, a .cnltlvator frame a Cardan joint connecting the cultivator frame with the tractor frame, cultivating members carried by the cultivator frame, means for operating the cultivating members from the engine and including a divided shaft and a Oardan joint connecting the members of said shaft, and a rod adjustable inlength, and universally jointed to the cultivator frame and the tractor frame, to permit of varying the direction of the axis of the cultivating members in relation to the line of travel. i

8. In an automobile cultivator, a tractor frame, a cultivating frame a Garden joint connecting the cultivator frame with the tractor frame, aiseries of cultivating members carried by said cultivating frame, a driving shaft carried by the tractor frame, an actuated shaft carried by the cultivator frame and operatively connected with the cultivating members, a'Cardan joint connecting the said shafts, a rod made in sec tions, a bar fixed to the tractor frame, one section of the rod being connected by a universal joint with said bar, and the other section having a universal joint connection with the cultivating frame, and means for adjusting the sections of the rod relative to each other to vary the length of the rod and thereby adjust the position of they cultivating members relative to the line of travel.

,9, In a cultivator, a tractor. provided with a frame having an engine thereon, a cultivator frame, a universal joint connection between the front end of the cultivator frame and the said tractor frame, a shaft carried at the rear of the cultivator frame, cultivating members carried by saidshaft, a shaft comprising members one of which is driven from the engine of the tractor and the other is opei a'tively connected with the shaft carrying the cultivating members, a universal joint connection between the members of said shaft, means for adjusting the cultivator frame .to vary the inclination of the shaft carrying the cultivatin' members relative to the line of travel, as eeladap'tcd to run at the bottom'of the furrow to prevent side movement, and means for adjusting the shaft carr ing said wheel accordin tot-heposition 0 the shaft carrying the on tivating members. f

Inatestimony whereof I- have signed my namefto this specification, in the presence of two subscribing witnesses.
